Possible to require specific products in order to be able to checkout?

-- HikaShop version -- : 3.1.1
-- Joomla version -- : 3.7.4
-- PHP version -- : 5.6.31

Got a odd request to require a minimum of 4 specific, different products in any given order.

I see I can set a minimum of just 4 products (of any kind) per order via shipping methods.

But I see no way to require specific products in an order.

Is there a way that I'm missing or would this require a custom plugin or changes to a particular view?

Hello,

Due to the specificity of the "restriction", it would require a custom plugin.
Best would be to use "onBeforeOrderCreate" trigger ; check the cart content and authorize or not the rest of the workflow thanks to the " $do " variable in the trigger.
